Answer:
The cleaning up of Lake Washington didn't occur overnight. It started with the process of providing scientific information to the public and the public decided to take action.
The action was persistent and the results yielded took a long while to materialize properly.
Upon receipt of the information from scientists that a particular bacteria was responsible for damaging the ecology of the water body, the public resorted to conveying all effluents to a treatment plant rather than dump same in to the Lake.
Cheers!
Answer:
Bone marrow.
Explanation:
Hematopiesis may be defined as the formation of the blood cells by the precursor stem cells. This process occurs in the bone marrow, thymus and liver.
The red blood cells are enucleated cells with the minimum span of around 120 days. These cells are processed and destroyed in the spleen. The iron is recovered from the red blood cells and sent again into the bone marrow for the production of new blood cells.
Thus, the answer is bone marrow.
